3D Realms, the studio that spent more than ten years working on Duke Nukem Forever, has dropped their lawsuit against Gearbox Software, the company that purchased the rights to the game and finally published it.

The lawsuit was initially brought earlier this year after 3D Realms claimed Gearbox had refused to pay more than $2 million owed to them from royalties and advances Gearbox received from publishers for the game.

In an email sent to Kotaku todayby Gearbox, 3D Realms co-founder Scott Miller had the following to say:

To Whom It May Concern-

After reviewing evidence regarding our business affairs, and without any money exchanging hands, we have satisfactorily resolved any and all differences that we perceived against Gearbox.

In all sincerity, we regret the misunderstanding that instigated our lawsuit. Now that we better understand—and appreciate—the actual nature of our business matters, we have voluntarily withdrawn our claims against Gearbox, with genuine apologies to Randy for any damage that our lawsuit may have caused to the relationship.
